IMPROVED BLOCK FOR CAR-BRAKES.

Specification forming part of Letters Patent No. 51,298, dated December 15. 1865.

To all whom it may concern:

Be it known that I, BARTHOLOMEW DE VOUT, of the city ot'Harrisburg', county of Dauphin, State of Pennsylvania, have invented a new and useful Improvement forBrakeBlocks, Liners, and Hangers for Railroad-Oars; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being bad to the annexed drawings making a part ot'this specification, in which-- Figure I is a side view showing it hung to the cross-piece ot' the car-truck. Fig. 11 is a back view of the same. Fig. III is a sectional view out through the center of the block and liner. Figs. IV and V are the front and side views of the hanger.

The improvement consists of three parts, the hanger O and D, which is of wrought-iron, the brake-bloekB, and thelinerA, both ofcastiron. The part D of the hanger is firmly secured upon the cross-piece ot' the cartruck. The part 0 is attached to D by means of a pin, P, secured with akey, which allows itto swing or move readily. Thelower end ot'O is formed as shown in Figs. 11 and III. The liner A has ledges L and L cast on the top and bottom made to fit the upper and lower ends of the brake-block. In the upperledge, L, a groove is made, as shown at g, as shown on Figs. II and III, into which the portion 0 of the hanger 0 works, thus securing the, liner to the block and preventing the liner from coming off. The portions of the liner at the upper and lower end, (I and d,is cast full, so as to bear against the ends of the brake-block.

The liner is removed or attached by first removing the key of the pin P, and then withdrawing the pin P, which lets fall the part (J of the hanger, which falls clear of the groove 9 in the liner. The liner is then removed or attached, the brake-blocks being held in position by stay-chains, with which most brakes are provided.

that I claim as my invention, and desire to secure by Letters Patent, is-

The form and construction of the brakebloek and liner, together with the form of the hanger and the mode of securing the liner to prevent its coming off and to expediteits re moval and replacement, as substantially set forth and described.
